The hospital that was the nexus of several storylines in the flash-sideways in Season 6 was the Nuuanu location of the Rehabilitation Hospital of the Pacific (226 North Kuakini Street). Jack and Juliet worked there, and patients included Claire, Locke, Sun, and Sayid’s brother. Visitors included Kate, Sawyer, Sayid, Nadia, Helen, and David. The location was also used to portray the care home where Anthony Cooper lived (“The Candidate, Ep. 6×14). (continue reading…)

The office building where Claire went to visit the adoption agency, and where Desmond introduced her to his lawyer Ilana (“The Last Recruit,” Ep. 6×13), was Pauahi Tower in downtown Honolulu (1001 Bishop St.). The lobby was transformed with a check-in desk and a sign that read “Constellation Tower.” Desmond and Claire took the escalator to the mezzanine level, then took the elevator to the 15th floor. Jack and his son David later arrived for the reading of Christian’s will. The mezzanine level also stood in for Heathrow Airport when Sayid was apprehended (“The Greater Good,” Ep. 1×21).

The Los Angeles office where Desmond goes to visit Widmore (“Happily Ever After,” Ep. 6×11) was built inside the ground floor of the King Kalakaua Plaza, also known as the former Niketown building (2080 Kalakaua Ave.). (continue reading…)

The “Airport Courthouse” where Charlie is bailed out by Widmore and met by Desmond is Hale Auhau (425 Queen St.), the home of the state Department of the Attorney General (“Happily Ever After,” Ep. 6×11). In the scene, Charlie and Desmond cross the street to a bar called “Jax,” played by Anna Bananna’s. (continue reading…)

The hospital where Sayid and Nadia go to see Omer, and where Jack is briefly seen passing in the hallway (“Sundown,” Ep. 6×06), was Hawaii Medical Center East, formerly St. Francis Medical Center (2226 Liliha Street). (continue reading…)

The hospital where Kate takes Claire when she goes into labor (“What Kate Does,” Ep. 6×03) is Hawaii Medical Center West, formerly St. Francis Hospital, at 91-2135 Fort Weaver Road. The street number on the building is briefly visible in the background as the camera follows Kate from the taxi cab. The interior scenes (featuring Kate, Claire, and Ethan) were also filmed here.

The State Museum of Cultural and Natural History, Bishop Museum, has served as a filming location for several episodes. The museum’s “Great Lawn” was where Eloise was staging the “fusion” concert when Desmond visited her in the flash-sideways (“Happily Ever After,” Ep. 6×11, “The End,” Ep. 6×17). The backstage area where Claire gave birth to Aaron was the Long Gallery inside historic Hawaiian Hall. The side of the Hawaiian Hall has also appeared as the London waterfront (“Flashes Before Your Eyes,” Ep. 3×08) and as a snowy street in Russia (“He’s Our You,” Ep. 5×10). (continue reading…)

The bustling international airport in Sydney (“White Rabbit,” Ep. 1×05, “House of the Rising Sun,” Ep. 1×06, Exodus,” Eps. 1×23 and 1×24, and “Two for the Road,” Ep. 2×20) was played by the the gleaming steel and glass Hawaii Convention Center, which does bear a striking resemblance to an airport (1801 Kalakaua Ave.).
